An investigation examined how temperature affects enzyme activity both when the enzyme is immobilised and when it is non-immobilised (free in solution). The product formed by the enzyme-catalysed reaction leads to a fall in pH. The graph presents the outcomes of the investigation. Which condition would produce the greatest yield of product?
- Aimmobilised, $37^{\circ}\text{C}$
- Bimmobilised, $75^{\circ}\text{C}$
- Cnon-immobilised, $37^{\circ}\text{C}$
- Dnon-immobilised, $75^{\circ}\text{C}$
